I'm wanting to add an interest component to a long term loan liability account. Understanding how the director's loan account works is fundamental to running a company and this article explains what you should know.Are you charging interest on your Directors Loan Account? I have some questions on how a Director's loan work in a BTL LTD Company, hoping someone experienced here can help answer. You can charge interest on your loan. For your company the interest counts as a business expense and is deductible from profits. Credit the loan account with rs. 1,00,000. Bank is real account. As the director of a limited company you can borrow money from the business (or lend money to it) and account for it as a director's loan. Putting some money into your limited company and wondering how to open your director's loan account?
